Be it known that I, Sorornnn citizen of the United ,itn the city of St..ln'mis State of l is r 1. invented a new and useful lie lient Vol Tire,of which {be following is n specification.

This invention relates in 2(1.'5.lll=lll vehiele lives and consists inthe novel constrmfi'rion disclosed and elaimed.

An object of the invention is to provide a. reinforced flexible milshield embeddd in a ease of elastic iii-ah in! which will pre vent thepermutation of the tire and which will not reduce in any uppreoiableextent the resiliency thereo With this and other appm'emfobjects inView, I- have prodi'roed a new article of manufacture comprising theparts of the novel design and arrangom" t hereinafter described andCll'illlli'ffl, 1- he being made, in the course of the dose Lion, to theaccompanying drawing, in r. rich like parts are indicated by likereference characters, and in which-- F igure 1. is o View of my improvedtire partially in cross seetion and partially in elevation. Fi 3 is aside elevation of u fr gment of the tire, a PUI'iiOD of ill) case bebroken away to disclose more clearly the manner in which. thereinforcing flexible metal shield is embedded therein.

In the embodiment of my ii'i\-'e1itioIi illustruted in the drawing 1indicaies the spokes 0f the wheel, which support a folly member 2, whichis fol-riled with a channel 3, adapted to receive the enlarged annularheads 4, formed on the case A, and is held in adjustment by the usualwedge block 5.

The case A, is of usual design and shape and is formed from somesuitable elastic ma-- terial such as rubber and is adopted to in case aninflated inner tube or it may he used as a single tube tire, in Wliiiiilcase the air pressure is introduced within, the same as will be readilyundorsliomi by those familiar with the art.

The member B, is embedded in the case A, and is of novel constructionpeculiarly adapted as a shield and reinforcement for the ease A, toprevent the penetration therewithoni; detracting from the usual alas 1liicify or resiliency thereof. The member B oonr rises an annular frameconstructed pre' erably of some durable flexible metal, such forinstance as spring brass. The side walls of the shield B are doubled orfluted to form the folds or plaits 2' adjacent to their free or openends. The said walls of the frame B extend substantially parallel wifih'the walls-of the case A for a distam-3e as shown at 8, and then are bentsabsrnntially at right angles as shownalz The folds 0r plaits 7 are soarranged that their walls are substantially at right angles with theside walls of the case. Above the tread of the case A, the shield B isbent so as to form the inwardly extending fold 10 and the outwardlyextending fold 11, the older ends thereof being joined by the .wall 12parallel to the tread. Thus the shield, at his point presents threeseparated thicknesses of metal parallel with the tread, for

it. will be seen that in use the lines ofipressure will alwaysbetransverse to the walls of the :folds and,-therefore, always. arallelwith the flexed or bent ends thereo which fore, that the resiliency ofthe elastic case will not be appreciably impaired, but that it will bedifficult for any sharp articlo to penetrate the shield. Moreover, theshield constitutes an efiective reinforcement for the case and will thusprevent a blowing out of the case from the an pressure within.

1 am aware that changes in the construction within equiv'alenb limitsmay be made and I do not restrict myself therefore to exact details, but

What I 'claim and desire to secure by Lettors Patent is:

1. A. vehicle tire comprising an elastic on so, and a resilient annularmetal frame embedded therein, said frame being provided with a, seriesof ploits 0r folds at each side, the walls of which are substantiallytransverse. to the walls of the case, and being bent substantially thefull width thereof. Thus impart resiliency to the shield and, there- Inwitness whereof, I have signed this peeification' in the presence of twosubscribmg witnesses. l,
